Power Supply in EX2300 Switches
The power supply in EX2300 switches is built in along the rear panel of the chassis, with
an AC power cord inlet or DC power terminals on the rear panel to connect power to the
switch.
NOTE: After powering on the switch, wait for at least 60 seconds before
powering it off. After powering off the switch, wait for at least 60 seconds
before powering it back on.
Table 12 on page 27 lists the power consumed by each EX2300 switch model.
